(Rom 8:9) “But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of His.” This verse is the key verse to understanding the chapter. The saved are “in the spirit”; the lost are “in the flesh”. One cannot please God till they repent (turn from their sinful life), ask forgiveness and the gift of Everlasting Life through the blood and the resurrection of God’s Son. Then one’s spirit is given life and the Holy Spirit seals the soul.
